Stop there. The coming few minutes decide it more than anything else: petrol in a diesel that has not run generally comes down to draining then purging, right there. Anywhere you happen to be around West Calder, this is the order things run from here. ## Minute one: petrol in a diesel, motor off Before anything else, these — following this sequence. - Keys out of the ignition. Turning the ignition on can be all it takes to prime the system, while priming draws petrol out of your tank towards the components it damages. Leave it off altogether. - No diesel on top. More fuel in removes none of that petrol — it only makes you with more of the same mixture. - Hazard lights on. If you're at all near moving traffic, make your car simple to see before you do anything else. - Off the pump by hand. On a forecourt, ask the attendants to help you roll the car clear of the petrol pump. Do not fire it up to shift it, however short the distance. - Hold on to your receipt. It shows which fuel got in plus roughly how much, which is the first thing we will ask. Still on the move when you realised? Come off the M8 at the next junction if that is where you are, under 3 miles from West Calder, and pull over somewhere safe rather than pressing on to the services. Then start at stage one. ## Has it run yet? The fork in each West Calder fuel drain What happens next rests on one answer, and just one. Not run, not even once: - The petrol is still in the tank and nowhere else. - The job is a simple drain and a flush, usually done where the car stands. - This is the best spot to be in, and the reason step one matters. If it has been started, even for a moment: - Out of that tank, past the filter, into the lines: that's how far the petrol has got. - Run it farther and that petrol gets to the fuel injectors, having passed through your pump first. - The farther it went, the larger the job — your lines, the filter, and now and then more besides. Petrol doesn't lubricate. Diesel does, protecting your high-pressure pump and injectors as it passes through, which is why the line sits where it does. Nothing is damaged by petrol that is just sitting in a tank. As soon as it's pumped, petrol starts wearing whatever moves it. ## Before you call about petrol in a diesel around West Calder: what our engineers need A little planning is the difference between a van that finds you and a van that circles. - The ideal start is a postcode — one starting EH55 8 — for where you have stopped. - Wherever you have pulled up, the road's name is useful — whether that's Gloag Place or somewhere else — and so does the name of a car park. - Describe a car park by what it serves — the one outside Scotmid, for example — and it's much easier to find. - That it's a diesel, plus the make and model of the car. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate West Calder page. - The amount: your receipt's litres, or otherwise how long you held the nozzle in. - The mileage it covered, and how heavily, if it ran at all. - The owner may have to authorise the work under some hire and company contracts — so it's faster to settle whose vehicle it is before our technicians arrive. Then call 0333 366 0103. If it can wait — the car is at home and going nowhere — works too. ## While you wait for a fuel drain in West Calder Help, however well meant, is what does the harm whilst you wait. So hold to these. - Safety before the vehicle. If it has stopped somewhere unsafe, get yourself away from the traffic and wait away from it. If it is safe where it is, wait with it. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll it a few yards. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive lifts the petrol. - Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank stays where it is regardless. - Ignition remains off. Even for your radio or your windows. ## Step by step: your fuel drain when the van gets there - Fuel, quantity, whether it's run: those replies decide this job, and that is why we give a price after them rather than before. - Out of that tank comes the contaminated blend: the tank is cleared. - If it ran, the lines are carrying petrol that has shifted beyond that tank — so they're flushed. - The fuel filter is sorted. Cleared, or swapped where the vehicle has a workable one. - Clean diesel in, and your system primed. - The start. With clean diesel in and your system bled, it's fired up and checked to confirm it runs smoothly. We wait until it is running on new diesel. If it has been caught soon, lasting damage is very unusual, and the car goes back to normal use right away. ## After your fuel drain: back on the road in West Calder - Drive normally. There is nothing special to do after it's been started on clean fuel. - Pull over and ring us back if anything seems wrong early on — a light on the dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - An insurer, a fleet manager or a hire company may ask what was done, so hold on to your paperwork. - Next time, check the petrol pump. The label, not the colour of the handle. ## About West Calder West Calder is a village situated on the riverside in West Lothian, with a mix of flat housing and other residential properties, and is located near Mossend, Freeport Village, and Polbeth.
